中文摘要	运用土壤粒径组分质量分布原理与分形理论,通过野外调查与室内试验分析,对太行山南麓地区4种林龄栓皮栎林下土壤粒径分形特征与养分特征进行研究。结果表明,1)不同林龄栓皮栎土壤颗粒质量分布差异明显,随栓皮栎林龄增加,黏粒、粉粒含量呈上升趋势,沙粒含量随林龄增加而减少; 2) 4种林龄栓皮栎林下0 ~ 40 cm土壤粒径分形维数D在1.35 ~ 2.61之间,均值为2.14,其分形维数与土壤黏粒、粉粒含量呈正相关关系,与沙粒含量呈负相关关系; 3)不同林龄栓皮栎的土壤理化性质存在差异,速效磷与有机质含量40 a生高于10 a生,全氮含量差异不明显,土壤中全氮、速效磷、有机质含量均与分形维数D呈正相关关系。
英文摘要	In order to describe the fractal characteristics of soil particle-size under the influence of Quercus variabilis which is in different age of growth in the semi-arid area of Taihang Mountain,this paper,using the principle of soil particle distribution and fractal theory,through field investigation and laboratory analysis,studied the fractal characteristics and nutrient characteristics of soil particle-size under four different ages of Quercus variabilis in Taihang Mountain.The results showed that,1) The distribution of soil particle-size in different ages was significantly different,and the content of clay granules increased with the increase of age,and the content of sand grains decreased with the increase of age; 2) The fractal dimension ranged from 1.35 ~ 2.61,and the mean value was 2.14.The fractal dimension was positively correlated with the soil clay content and negatively correlated with the sand content; 3) The soil physical and chemical properties were also significantly different.The content of available phosphorus and organic matter of 40-year-old Quercus was significantly higher than that of the 10-year-old,and the content of total nitrogen was not significant.The contents of total N,available phosphorus and organic matter were all positively correlated with the fractal dimension D.
